1D Kinematics and Free Fall

Front

What is the velocity of an object at its highest point when thrown straight up at 60 m/s?

Back

0 m/s

Front

What happens to an object’s motion when both velocity and acceleration are negative?

Back

The object speeds up.

Front

What does a horizontal line on a distance-time graph represent?

Back

Constant Speed.

Front

If a ball is moving downwards, what direction is the acceleration vector?

Back

The acceleration vector is downwards.

Front

How far does an object with an initial velocity of 3.50 m/s and a constant acceleration of 1.80 m/s² move in 5.00 s?

Back

40.0 m.

Front

Define acceleration in the context of 1D kinematics.

Back

Acceleration is the rate of change of velocity per unit time.

Front

What is the formula for calculating distance in uniformly accelerated motion?

Back

d = v_i * t + 0.5 * a * t², where d is distance, v_i is initial velocity, a is acceleration, and t is time.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only.

Front

What is the acceleration due to gravity near the Earth's surface?

Back

Approximately 9.8 m/s² downwards.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.
